In this episode, Leslie talks about how sound is transferred to the inner ear. Because there is fluid inside the cochlea, impedance matching has to take place for the vibration in the fluid to accurately represent the sound that you are hearing.

In this episode, Leslie talks about how we hear sounds. From the external ear to the eardrum, down to the 3 bony ossicles, then to the cochlea to be sent as signals towards the brain, it is all explained in this video.

In this episode, Leslie tells us about on center, off surround ganglion cells. See how the configuration of rods with respect to the ganglion cell’s receptive field influences the type of response we get when those rods are stimulated.

In this episode, Leslie explains more about the connections between rods and cones to bipolar cells, and between bipolar cells and ganglion cells. He also describes how these connections determine the receptive fields of each ganglion cell. Enjoy!

After the rods and the cones, there are a few other important cells involved in visual processing. In this video, Leslie explains about how the bipolar cells and ganglion cells contribute to this process.

In this video, Leslie explains how rods and cones work, using the rods as an example. Watch to find out how rhodopsin, transducin, and phosphodiesterase, all play a major role in the process of vision.
